DETACHABLE RUBBER HEEL FOR BOOTS AND S32-ICES.

Specification of Letters Patent.

riginal application filed January 20, 1910, Serial No. 539,064.. Divided and this application filed February To all 4whom it may concern.'

Be it known that I, CHARLES H. CHAPMAN, a citizen of the Uniied States, residing at lVinchester, in the county of Middlesex and State ot Massachusetts, have 'inventedA tion in matters or' detail relating to the application ot the heel to the boot or shoe and its removal therefrom, and otherwise.

The invention consists in providing the metal heel plate with guides and stops for the connectino pin, whereby a shorter pin than that use@ in the parent invention may be used and wholly concealed and effectively retained within the rubber heel when in use; also in using hollow or tubular rivets for anchoring the heel plate in the rubber; also in providing means for accurately en gaging the connecting pin to discharge it when the heel is to be detached; and also in modifying the lips of the clip so as more readily to find and engage the holes in the heel plate, all as I will proceed now more particularly to set forth and finally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure l is a top plan view of the heel without the clip. Fig. 2 is an elevation looli'ing at the breast, partly bro ren out to show the riveting. Fig. 3 is a bottom plan view of the heel-plate. Fig. l is a side elevation of the heel plate and rivets, indicating by dotted lines the hereinafter described vertical movements of the rivets relatively to the heel plate. Fig. 5 shows, on a larger scale, in elevation and plan view, the heel plate attaching rivets. Fig. 6 shows in top,.plan, edge and end views, the clip. Fig. 7 is a top plan view of the comple e heel.

is a central vertical longitudinal section of the complete heel, including the clip for connecting with the boot or shoe sole, and showing one of the marking pins in place. Fig. is an elevation or' the connecting pin.

The heel 1 may be of the usual shape, and composed of rubber. In fthe hollow of the heel is a plate 9. of sheet-metal, of less area than the heel. This plate 2 is provided with a series of edge holes 8, in which are arranged rivets 4, the holes being enough larger than the Shanks of the rivets to permit relative vertical and lateral movement oi: the rivets. The plate is also provided with holes 5 preferably arranged in two longitudinal parallel rows. Transversely arranged rectangular holes 6 are made in the plate at its breast end, and va transverse elliptical hole 7 is made in said plate at its back end. The plate)J with the rivets l arranged therein substantially as shown in Fig. 1, is arranged so as to have the rubber ot' the heel vulcanized about it; the heads of the rivets serving as anchors to anchor the plate firmly to the rubber, as indicated in Fig. 2, and yet allow relative vertical and lateral movement of the heel and rivets due to the vertical and lateral movements of the rivets and the resilience of the rubber in use. The rivets 4 are of the tubular or hollow variety, by preference, for lightness and facility in upsetting.

During the molding operation two or in the rubber heel at opposite sides and ends, to receive marking pins S,--see Figs. 1 and 8, and these marking pins are ai. .inged in the holes so that their points projectsome what above the plate 2, and then when the heel is to be applied to the sole, the heei, constructed as already described, and pro- 'vided with these marking pins, is pressed more holes in line with the holes 5 are formed marking pins 8 in the heel. Nhen the solel `has been properly marked, then any suitable fastening nails or other devices 15 are driven through the holes 14 in the clip and into the sole, so as to secure the clip accurately to the sole. In order that the clip may firmly engage the heel plate 2, it is provided with a downwardly projecting lip 16, having in it a -A hole 17, said lip 16 being designed to extend through the hole 7 in the heel plate and into the rubber of the heel; and if necessary, or desirable, .the-rubber portion'may be provided with a cavity 18 to receive the projecting ends of the lip 16, and similar cavities may be made in the rubber body adjacent to the holes 6 to receive the offset lips 19 at the opposite end of the clip. These lips 19 are depressed from the plane of the clip and have a double outward and downward curve so as most efficiently to find and pass through the holes 6 Vin the heell late and underlie their edges, therebyto e ect a firm engagement of the clip and heel plate. This engagement of the lips 19 with the heel plate is first eifected,and then the lip 16 is passed into the hole 7, after which the pin, such as an ordinary wire nail 20, is drivenV longitudinally through the heel from its breast i toward its back and between the lips 19 and in line to engage the hole in the lip 9, being guided thereto by and between the lugs.11,

and thence extending in and through the hole in the lip 16 of the clip, until its head is' arrested :by the lugs and snaps into the hole 12, by which, under the tension between the clip and heel plate, it is held securely against accidental displacement. The pin is wholly concealed within the heel. The hole in the rubber for the connecting pin may be formed in molding the heel, by means of a core, or it may be otherwise produced. This hole is slightly smaller than the connecting pin and closes upon it so as to greatly retard its escape and practically'prevent its accidental loss.

As a convenient means for finding the pin and driving it out, so as to disconnect the heel itself from vthe clip, I provide the pushpin 21 having the tapered bore 22 in its tip to engage the point of the pin 20 and a head 23 by which pressure may be applied to the push-pin to drive 'out the connecting pin. The heel plate and its rivets may be copperplated in order to vulcanize the rubber firmly about the metal parts.

The operations of attaching and removing the heel are deemed to have been made plain by the foregoing, and for further details and for a further' statement of the advantages of the invention reference is made to the specifications of the cases hereinabove mentioned. l/Vhat claim is s 1.
